Abstract:
Biological characteristics of an early maturing bud mutation ‘Gala’ apple were compared with the normal one as the control.The results showed that the phenological period of the early bud mutation ‘Gala’ apple was mainly consistent with the normal ones but the mature period about 25 days earlier.The bud mutation had shorter tree bodies，more branches and lower growth rate of trunk diameter.The length of internode，the width and thickness of leaf were 1.07，1.16 and 1.17 times than the control，respectively.There was no difference in the length of branch，leaf and petiole.The length and width of petal，lengthways and transverse of anther diameter，length and diameter of anthocaulus，germination rate of anther，and the size of corolla were 0.87，1.16，0.94，1.14，0.63，1.49，0.70 and 0.87 times than the control，respectively.The average fruit weigth was 206.2 g，which was 25.3% higher than the control.The content of soluble solid，soluble sugar and soluble acid were 13.87%，5.55% and 0.1%，which was 4%，9% and 66.6% lower than the control，respectively.The sugar acid ratio was 56，which was 267% higher than the control.The fruit surface was covered with striped red equably.In conclusion，the early maturing ‘Gala’ was a mutation with excellent comprehensive properties.
